Abstract

The invention provides a self-dilution aerosol screening calibration apparatus. A aerosol gas to be calibrated is driven by a calibration fan to enter a neutralizer and a condenser for neutralization and temperature control; the aerosol gas passes through a main inlet pipe to be delivered into an electric classifier by an inlet flow controller; uncalibrated aerosol is introduced through a bypass outlet pipe into a diluter to obtain diluent gas, and the diluent gas enters the electric classifier through a bypass inlet pipe such that the diluent gas and the aerosol to be calibrated are mixed and diluted, and the mixture undergoes electric screening in the electric classifier; the aerosol which satisfies particle size range reaches a calibration inlet pipe and is driven by the calibration fan to be sent into a particle size instrument and a particle concentration meter inside a steady calibrator to be calibrated; aerosol exhaust gas left after calibration is filtered through an exhaust gas collector and then discharged; and a computer controller automatically controls the whole calibration process and detection through data line connection. The invention has the following beneficial effects: high-precision steady calibration of small granular aerosol can be carried out to meet special requirements in fields of environmental science, military medicine, inhalation toxicology, material science and the like.
